Barcamp session idea

There's an idea for a BarcampCHS session brewing in my head. Something along the lines of open source software and amateur radio. There's a fair bit of it out there, most of which is something I'm interested in learning more about (like GNURadio). What better way to make yourself learn about something than to try to give a presentation on it, right?

The idea isn't very well formed yet and may or may not happen, but it's there. I've got until November to figure it out. Plenty of time, right?
